Microwave imaging is an active area of research that has garnered interest over the past few
years. The main desired improvements to microwave imaging are related to the …

With the prevalence of breast cancer among women and the shortcomings of conventional
techniques in detecting breast cancer at its early stages, microwave breast imaging has …

Ground penetrating radar (GPR) is a special type of radar, which uses electromagnetic (EM)
wave to detect the buried objects in the shallow subsurface. The overall efficiency and …

Since the US Federal Communications Commission (FCC) opened the spectrum from 3.1 to
10.6 GHz for unlicensed radio applications with an EIRP of up to 41.3 dBm/MHz, numerous …

Low-profile directional ultra-wideband (UWB) antennas are strongly demanded in many
UWB applications. However, few such UWB antennas have been reported. To meet the …

An elliptical monopole based third iterative fractal antenna for super wideband applications
is investigated in this article. It consists of microstrip line fed three iterations of elliptical …

A loaded ultrawideband unidirectional folded triangular bowtie antenna is proposed for
ground penetrating radar (GPR) applications covering the (0.5-3 GHz) frequency range. The …

A high gain low-frequency bow-tie antenna with artificial magnetic conductor (AMC) and
metamaterial lens for ground penetrating radar (GPR) is proposed. First, a bow-tie antenna …

An arc-shaped distributed multilayer capacitive loading structure combined with resistive
loading is presented in this paper to enhance the radiation performance of folded bowtie …

Bowtie antennas are ubiquitous in practical ground-penetrating radars. In spite of having a
wide impedance bandwidth, boresight gain of these antennas is small and the main beam …
